Media Manager status code 21
Message: cannot obtain daemon lockfile
Explanation: vmd (NetBackup Volume Manager daemon on UNIX and Linux; NetBackup Volume Manager service on Windows) or the operator request daemon or service cannot obtain an internal software lock.
Recommended Action: Check for the existence and permissions of the lock file itself and the lock file directory: /usr/openv/volmgr/misc/vmd.lock (UNIX and Linux) or install_path\Volmgr\misc\vmd.lock (Windows). Create the directory or folder and adjust the permissions as needed so that vmd can obtain the lock: /usr/openv/volmgr/misc/vmd.lock (UNIX and Linux) or install_path\Volmgr\misc\vmd.lock (Windows).
